networkmanager and mac80211

[dragoran <drago01 gmail com>]

Hello,
while testing iwlwifi I found two bugs in nm:
1) when using a mac80211 driver like iwlwifi it shows
speed : unknown for the wireless connection
2) it always reports 100% for signal strength
see http://marc.info/?l=linux-wireless&m=117809490027074&w=2
else it works fine:
detected my wpa enabled ap, asked for the password and connected.
(I was using nm 0.6.4 on FC6 x86_64)
